A police chase early this morning reached speeds of 105 mph across central and east Denver, with suspects ramming an undercover officer’s truck before crashing in Adams County.

Abandoning their two vehicles, the suspects led police on a foot chase through fields near Interstate 270 and York Street before five of them were captured. Two others remain at large and are armed and considered dangerous.

Later in the day, police arrested two juveniles suspected of being accomplices. Police said they believe the nine people are part of a large auto-theft ring.

Miraculously, no one was injured in the wild, 25-minute chase that traveled in the wrong lanes of traffic on Colorado Boulevard, as well as the wrong direction up 13th Avenue. Police radio chatter was recorded on scandenver.net and released publicly this afternoon.

The chase began just after 2 a.m. today, when suspected members of an auto-theft ring spotted an undercover surveillance officer videotaping them at a gas station at 50th Avenue and Federal Boulevard.

Two suspects, in a stolen silver Dodge pickup truck, drove right at the undercover officer, who fled in his black Dodge Ram pickup truck onto eastbound Interstate 70. He immediately radioed for help from marked patrol cars.

“Get ’em over here,” the undercover officer, identified only as Joe, radioed at 2:02 a.m. “They’re right on my a–.”

Another officer interrupted: “OK, Joe, can you get off on southbound 25?”

“I don’t care, I just need some cops here. … They’re right on my a–, pulling up next to me.

“All right, I just hit the brakes. I’m going to be southbound on I-25. I need cover Code 10 (with emergency lights and sirens). … These guys are armed and dangerous.”

A number of patrol cars set up on Interstate 25, one at 20th Avenue, one at Colfax Avenue and one at Sixth Avenue.

Somewhere between Colfax and Eighth Avenue, the suspects rammed the officer’s truck several times.

At this point, a supervisor radioed that a chase was authorized because the suspects had rammed the officer.

As patrol cars with sirens blaring and lights flashing joined in the chase, the suspects suddenly switched from being the aggressors to being the hunted.

The silver Dodge got off I-25 at Alameda Avenue, went across the overpass and back onto I-25 northbound, with police in pursuit.

It was unclear what happened to the undercover officer from this point.

The suspects exited I-25 onto eastbound Colfax, shot up to somewhere near Broadway, worked their way north to Park Avenue West, then turned southeast back across Colfax to 13th Avenue.

At Franklin Street, they turned the wrong way eastbound up 13th — a one-way street — reaching 75 mph as they crossed Gaylord and Josephine streets.

At Colorado Boulevard, the silver Dodge turned south, crossing over the median at Ninth Avenue and traveling south in the northbound lanes.

At Third Avenue, the suspects reversed direction and headed north on Colorado, again crossing over the median into the southbound lanes while still traveling north.

The radio chatter wasn’t clear how long the suspects stayed in the wrong lanes, but at 25th Avenue, a police officer radioed that he was traveling 90 mph. At Bruce Randolph Avenue (34th), the officer said he was traveling at 95 mph.

It was near here that a second car entered the chase, a green Lincoln Continental. Police spokesman Sonny Jackson said the suspects apparently called friends and asked them to help by crashing into the police cars.

The suspects crossed over I-70, where Colorado Boulevard becomes Colorado 2. At 60th, they turned west, eventually crashing both the Lincoln and the Dodge truck in front of a home at 6580 York St.

Seven suspects fled on foot. Five eventually were captured with the help of K-9 dogs, a helicopter and the Commerce City Police Department.

Later in the morning, police arrested two juveniles suspected of being part of the auto-theft ring.
